1 Overview
1.1 Introduction
The F-PRO is a microcontroller-based relay providing comprehensive Overcurrent / Earth Fault
Protection, Sensitive Earth Fault / Restricted Earth Fault, Auto Reclosing, Circuit Breaker Failure,
Broken conductor, Thermal Overload, Negative Sequence Overcurrent, Inrush Restraint, Trip
Circuit Supervision, Metering, Breaker Monitoring functions suitable for distribution
applications.
Hyper Terminal is the online tool, which enables the user to:
Change, review & retrieve relay settings
View event and fault information
F-PRO Offliner is the offline tool which enables the user to:
Create and review relay settings
The primary protection provided is overcurrent based. A library for these overcurrent functions
provides commonly used IEEE and IEC inverse curves. Since the curves are equation-driven, the
user can choose to enter equation parameters directly to create other overcurrent curve shapes
as needed.
To provide a complete package of protection and control, F-PRO provides other functions such
as:
Breaker failure Protection (50BF)
Multi-shot Auto Recloser (79)
5 ProLogic statements
2 Setting Groups
Hyper Terminal is the Windows graphical user interface software tool used to:
Retrieve event logs and fault logs
Manage settings

AC Current Inputs
F-PRO is provided with terminal blocks for up to 5 AC currents (3
Phase Current, 1 Neutral and 1 SEF). 1A and 5A are seperate
terminals, 1A or 5A CT Secondary is Site Selectable.

External Inputs
The F-PRO relay has 4 external inputs with a factory selectable
voltage level. External DC voltages of either 24 volts, 48 volts, 110
volts, 220 volts nominal are available depending on the ordering
code.
Relay Inoperative Alarm
Output
If the relay becomes inoperative, then the Relay Inoperative
Alarm output contact closes. Output Contact 6 may be
configured as Relay Inoperative Alarm Contacts. During the relay
inoperative period, all tripping functions are blocked.
Output Relay Contacts
The F-PRO relay has 6 output relay contacts. Each contact is
programmable and has breaker tripping capability. All output
contacts are isolated from each other. All the contacts are
provided with settable dropout timers (0-1 sec) - applicable for
self reset.
If function reset time & the output contact reset time both are
set in the IED; then, the higher value will be taken for relay drop
out. Example: 51 function is chosen with reset DTL delay 0.5 sec
and the output contact dropout time is 0.8 sec, then 0.8 sec will
be the dropout time of the output contact.

2 Setup and Communications
2.1 Introduction
This chapter discusses setting up and communicating with the relay including the following:
Power supply
Communicating with the relay using a direct serial link
Using Hyper Terminal 
2.2 Power Supply
A wide range power supply is standard. The relay power supply is provided with nominal
operating ranges of:
20 to 60Vdc
80 to 300Vdc / 100 to 250 Vac, 50/60 Hz.
To protect against a possible short circuit in the supply use an inline fuse or circuit breaker with
a 5A rating. Ensure that the chassis is grounded for proper operation and safety.
There are no power switches on the relay. When the power supply is connected, the relay starts
its initialization process and takes about 5 seconds to complete the boot and glowing the green
LED for relay functional.
Case Grounding
WARNING!
Ground the relay to station ground using the case-grounding terminal at the
back of the relay, for details see Figure 1.3: F-PRO Rear View on page 1-4.
2.3 Time Source
The F-PRO relay supports the use of manually configurable system time based on a free running
internal oscillator. The internal free running oscillator is present on the F-PRO.

2-2 F-PRO116 User Manual E00116R01.00
2.4 Communicating with the F-PRO Relay
Connect to the IED for access its user interface and supervisory control and data acquisition
(SCADA) services by:
Front USB 2.0 interface (user interface and maintenance)
Rear panel serial link (RS485 serial link )
The relay has a front panel USB port (COM 1) and 1 rear RS485 Port (COM 2) to provide direct
access to IEC103/Modbus services.
The relay user interface is accessed through the Hyper Terminal.
2.5 USB Link
The PC must be appropriately configured for USB communication.

USB Driver Installation
To create a USB link between the relay and the computer, connect the PC to the front USB port of
the F-PRO. The STM32 VCP Driver needs to be installed in computer as follows:
STM32 VCP can be downloaded from ERL website.
http://www.easunreyrolle.com/product.php?id=1096
Then go the Device Manager to check the port detect.
Start > Control Panel> Device Manager > Other devices
In this path a small icon with the name of STM32 VCP will be found (If user removed USB cable,
this icon will be removed from that path)
Next to that Right click on the STM32 VCP icon and select "update Driver software".
"Update Driver Software STM32 VCP" Window will appear.
In that select "Browse my computer for driver software".
Now Browse the STM32 VCP driver folder the path where it was saved.
Example; D:\STM32 VCP_driver\win7 (for Windows 7)
And click the next button. Now the Driver Installation will be started and click close after the
Installation is done.
Now check ports in Device Manager
Start > Control Panel > Device Manager > Ports (COM & LPT)
Can find "STM STLink Virtual" port, note COM port number which is installed Ex: COM 6.

2.8 Accessing the Relay’s SCADA Services
The relay supports IEC 60870-5-103 slave and Modbus slave SCADA protocols as a standard
feature on all F-PRO series relays. The Modbus implementation supports both Remote Terminal
Unit (RTU) binary and ASCII modes and is available through a direct RS485 serial link.
The relay Port 2 is dedicated for use with Modbus slave, IED 60870-5-103 slave protocols. The
serial Port uses standard RS-485 signaling. An external RS-485 <-> RS-232 converter has be used
to connect to an RS-232 network.

Protocol Selection
To select the desired SCADA protocol go to F-PRO Offliner SCADA
communication section. Select the desired SCADA protocol and set the
corresponding parameters..
Communication
Parameters
The serial port's communication parameters are set in the F-PRO Offliner
SCADA communication section. Both the baud rate and the parity bit can
be configured. The number of data bits and stop bits are determined
automatically by the selected SCADA protocol. Modbus ASCII uses 7 data
bits. Modbus RTU, IEC 60870-5-103. All protocols use 1 stop bit except in
the case where either Modbus protocol is used with no parity; this uses 2
stop bits, as defined in the Modbus Standard.
